TWO-WHEELED VEHlCLE.

SPECIFICATION forming part of Letters Patent No. 358,908, dated March 8, 1887.

Application filed July 30, 1886. Serial No. 209,553. (No model.l

To aZZ whom it may concern.-

Be it known that 1, I'IIATT XVILBUR, of Almont, in the county of Lapeer and State of Michigan, have invented certain Improvements in Road-Carts and Other Two-l/Vheeled Vehicles, of which the following is a speeification.

The aim of my invention is to provide a running-gear by which the body may be securely supported but permitted to rise and fall with an easy action when traveling over uneven ground, and to avoid the vibratory motion which is commonly imparted to the body by the movement of the horse.

The accompanying drawing represents the frame or running-gear of the cart constructed plan, the box or body, to which my invention has no special relation, being omitted in order to expose other parts to view.

Referring to the drawing, A A represent the two main wheels, of ordinary construction, mounted on opposite ends of the metal axle B, which latter is curved upward at the middle, as shown at a.

0 represents the thill, formed with or secured rigidly to horizontal arms or side bars, D, which are extended rearward and clipped or otherwise secured firml y to the ends of the axle, as shown at b.

E represents a horizontal frame of suhstantially a Y form suspended at its center by a.

link, 0, or equivalent connection from the arched portion of the axle. Atits forward end this frame is attached to a cross-bar, F, forming in effect a part thereof, the ends of which are provided with stirrups d, riding in slotted plates,stirrups, or equivalent horizontal guides e on the arms D. The purpose of this baris to maintain the frame E in a horizontal position and to prevent it from tipping or overturning G G represent two arched or' semi-elliptic springs located one at each side of the frame and extending longitudinally thereof, their forward ends being connected by links or otherwise to the extremities of the cross-bar and their rear ends connected by links f, or equivalent connections, to the rear arms of the frame E. Upon these springs,midway of their length, I propose to mount the box or body of the vehicle in any appropriate manner. I prefer to secure in each spring a 1011- gitudinal bar or bolster, H, and to connect the sides of the body to the ends of these bolsters by metal arms, such as are commonly employed in similar places. As these connections form no part of the present invention,

and as the body may be connected to the springs in any suitable manner, it is deemed unnecessary to illustrate these details herein.

It will be observed that under my construction the entire weight of the body will be received upon the springs G,transmittedthence to the frame E, and finally supported from the axle entirely, or practically so, by thelink c. The slotted connection at the front permits the body, springs, and frame Eto play freely forward and backward, thus relieving them from the vibrations which they would otherwise receive.

lVhile I prefer to construct the frame E in the form represented, it is to be understood that it may be modified in form at will, provided only it is adapted for suspension at the center by the links 0 and to sustain at its corners the ends of the longitudinal springs.

In some instances I have divided-or forked the forward end of the frame E, turning its ends outward to enter the guide e,as indicated in dotted lines, thus dispensing with the crossbar F.

Having thus described my invention, what I claim is 1. In a two-wheeled vehicle, the combina tion of the supporting-wheels, the axle, the thills having rigid connections to the axle,the frame Eand the links by which it is suspended centrally from the axle, the horizontal sliding connection between the front end of said. frame and the thills, and the longitudinal springs connected to the frame E, substantially as described.

2. In a two-wheeled vehicle, an axle having an upward curvature at the middle, in combi* nation with a spring-supporting frame suspended from the arched portion of the axle by a link, substantially as described, whereby the frame may be supported in a horizontal plane coinciding substantially with the ends of the axle.

3. In a two-wheeled vehicle, the combina tion of an axle, a frame, E, suspended mid- In testimony whereof I hereunto set my Way of its width from the axle, and two longihand, this 5th day of July, 1886, in the prestudinal springs passing above the ends of the enee of two attesting Witnesses.
